Specification of Letters Patent.

Application filed August 18, 1906. Serial No. 331,186-

of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and Auseful Improvements in Mortise- Locks; and I do herebydeclare the following to be a full, clear, and exact description .of

the invention, such as will enable others skilled in the art to which it appertains to vmakeand use the same.`

.My invention relates to improvements in mortise-locks,` the object being to provide means accessible from the outside of the lockcasing for dogging the outer-knob mechanism, combined with means for disconnecting the actuating means from the dogging mechanism when the door'is closed, thus absolutely preventing a release of said cloggingmechanism while the door is in its closed position.

` With this object in view myinvention consists in the parts and combinations of parts, las willbe more fullyl explained, and pointed Mout in the claims. f

In the accompanying drawings, Figure 1-is l removed, showing the dogging slide disengaged from the outer-knob mechanism. Fig. 2 is a view similar to Fig. 1, showing the position of the partswhen the door is closed. Fig. 3-is a view showing the dogging-slide in engagement with the fiange orroll-back of the outer knob, the parts being shown in their positions when the door Yis open; and Fig. 4 is a view similar to Fig. 3*, showing the position of the parts when the door is closed',

-In the drawings I have shown a spring llatch-bolt 1, .that can be retracted by a key through the engagement of the pivoted lever 2. with the cross-head 3 on the free end of the stem 'of the bolt and by inner and' outer knobs, each knob .being mounted on its own shaft, the two shafts being located end to end and connected so as 4to prevent endwise separation. Each knob-shaft is mounted in a roll-back adapted to engage shoulders on the pivoted lever .5, the free end of which engages orloverlaps the adjacent end of pivoted lever 2 and actuates the bolt through thelatter.

The key mechanism may be of -any -app p roved type; butthe lock as shown is designed for use with a Yale & Towne pin-tumgages the shoulder 4 on lever 2 and rocks the latter.

7 is an auxiliary bolt which engages the closing movement of the door and remains so while the door is closed. The sliding movement of the auxiliary bolt releases a springactuated deadlocking-lever 8, which when Vreleased is turned by its spring into the path of the bolt 1, as shown in Fig. 2, and dogs the bolt against movement.. As the door is opened the auxiliary bolt will be moved outgaging the beveled face10 vof the lever 8, will move the latter out of the path of bolt 1, and so hold it while the door remains open. The inner end of the lever 8 lies in the path of movement of the finger 11 of lever 2, so that 'when said lever 2 is turnedv eitherby the key v`lever 8 will be moved out of the path of bolt 1,`thus permitting the latter to be retracted.

vided' with a projecting flange 1 3, having a recess 14 for the receptionof the inner end of the deadlocking-slide 15.` This slide is suitably mounted to slide longitudinally and is provided at one side'with aprojection 16, to which is pivotally mounted the hook 17, which latter is connected to the ivoted lever `8 by the yoke 18. Thus IJit will e seen that when the lever 8 is moved on its pivot `the hook 17 will follow its movements.

Pivotally mounted within the casing is the rocking lever 19, to which the push-buttons 20'and 21 are connected. Push-button 21 is provided with an inwardly extending 1ntegral arm 22, which carries the finger` 23', the latter bein pivoted at 24 to said arm. Spring 25` is connected to said finger and tends to normallyhold it against the stud 25, inte ral with arm 22. .p l

hen the door is in its open position, the nose of the hook 17 rests between the rocking lever 19 and free end of the spring-pressed finger 23. If now push-button 21 be pushed in, the rocking of lever 19 will push button 20 out and also push against the free end of hook 17 and move it and the deadlockingslide 15 longitudinally and cause the slide to enter recess 14 in flange 13 and'deadlock the outer knob against movement. If the door strike-plate and is forced inwardly during the wardly by its spring, and its cross-head 9, en-

or bythe knobs, as heretofore explained, the

bler lock, the movable member of which eni The roll-back 12 ofthe outer knob is probe now closedwith the parts in the position last described, the movement` of the pivoted lever 8 to its deadlocking position, as eX- plained, will move the hook 17 toward the slide 15 and out of the path of finger 23, thus disengaging the deadlocking-slide 16 from the push-button mechanism of the lock and absolutely preventing any movement of the deadlocking-lever 8 through the medium of yoke 18 pulls the hook 17 over 'against the spring-pressed finger 23. If' after the door has been opened the slide be in its deadlocking position and the push-button 21 be out, by now pushing in on button 21 the finger 23 will be carried inwardly, and as it passes the nose of the hook 17 its spring forces it under the nose, and by now pushing in button 2O the free end of the finger, engaging the nose of the hook, moves it and itsattached slide 15 outwardly until the latter clears the recess 14 in flange 13, -thus releasingvthe outer knob and leaving it free to be rotated.

- With this improvement the bolt 1 is always deadlocked by the pivoted lever 8 against any vinstrument introduced .between the strikeplate andV the'face` late of the casing, and when the outer kno is deadlocked the act of closing the door disconnects the knob deadlocking-slide 15 from its operating push-buttons, thus-absolutely.preventing any movement of said slide until the connection between the slide and its push-'buttons has been restored by thel opening of the door, which may be done by the inside knob or the key from` the outside. f y

' The slide 15 is held against accidental longitudinal movement by the spring 27, the free end of which engages notches 28 in the sides-of 4vthe slide and bears therea ainst with suflicient pressure to prevent t e possibility of any a cidental movement of the slide 15. l

' ,X It is evident that many slight changes might be resorted to' in the relative'arrangement of parts shown and-dscribedwithout departing from the spirit-"and .scope'of my invention` Hence I would have 1t understood that I do not wishto confine myself-to the exact construction and' arrangement of parts shown and described; but,
